Overview

The TW2743 employs Tallysman’s unique Accutenna technology in a magnet mount, right hand circularly polarized antenna for the reception of all of the GNSS constellations (GPS L1/GLONASS G1/ Galileo E1/ BeiDou B1) plus Iridum: 1559 to 1626.5 MHz frequency band. It is specially designed to maximize the performance of Iridium Voice and Data Modems plus the upper GNSS band (1559 – 1606 MHz).

The TW2743 is switchable between the passive Iridium and the active GNSS antenna by changing the input voltage to the antenna. When the input voltage is less the 5.5VDC, the antenna will engage the GNSS antenna. To invoke the passive Iridium antenna, an input voltage above 5.5VDC is required.
